KenKen - One more case

Here is one more interesting strategy I discovered when solving one of my CleverClever puzzles.

The four-cell cage on the right shows all possible candidates of each cell. We can discard the 1 of (5,8) because the sum must be even and the three other cells only have even candidates. Then, as the 1 of row 5 can only be in (5,1), we can remove all other candidates from that cell and the corresponding candidates in the other cell of the cage.
